Where is the ETC installation location?
3 Answers
The ETC installation location is on the upper middle part of the front windshield horizontally, while for large vehicles such as trucks and buses, the installation position is on the lower middle part. The suitable installation position should be no lower than 1.2 meters and no higher than 2.5 meters in height, with an installation angle between 30 to 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof films, it may affect the signal transmission of the microwave communication link, and thus should be installed in the microwave skylight zone. Precautions for using ETC include: 1. The ETC transaction sensing range is 8 meters. To prevent issues with the ETC device of the vehicle in front, maintain a distance of more than 10 meters to avoid automatic payment for the preceding vehicle; 2. The ETC lane recognition speed is 20 kilometers per hour. Driving too fast may result in failure to read the vehicle device information, leading to payment failure; 3. When using a debit card to bind with ETC, insufficient balance may also cause payment failure.
Last time I installed an ETC device in my car myself, positioning it near the rearview mirror on the front windshield. It's generally recommended to place it slightly above the center of the glass. After installation, the device can quickly recognize signals at toll stations, saving a lot of time. The installation process is very simple: just clean the glass surface to ensure there's no dust, then secure it firmly with strong double-sided tape. I paid special attention to not placing it too low to avoid obstructing the view and affecting driving safety. It's best to avoid the main line of sight, such as the exact center point below the rearview mirror. During testing, I found that positioning it too high might expose the device to direct sunlight, causing it to overheat, while placing it too low could block the road view, so finding a balanced spot is ideal. Normally, I don't even notice it while driving—it's both aesthetically pleasing and practical. If the position isn't accurate, sometimes the signal may be delayed, requiring adjustment.
I have some research on automotive electronics. The ETC installation position is ingeniously designed, usually attached to the top center of the front windshield. This ensures the device's sensor faces directly forward, optimizing the signal transmission angle with toll stations and avoiding errors caused by tilting. Before installation, measure the flat area of the glass and use the provided adhesive strip to secure it firmly to prevent loosening. Note that the tilt angle should be controlled within 5 degrees; otherwise, the infrared signal may fail. In the long run, a position too high is prone to UV damage, while too low may obstruct the driver's view. Choosing a moderate spot can extend the device's lifespan. When installing it yourself, cleaning the glass surface is a crucial step to avoid impurities affecting adhesive strength. Once fixed in place, testing shows high passing efficiency, making it very convenient.
